not really looking on a bike preference, i read the intro post and i am not looking for some radical bike, not even looking to go over 100 with it. just want it to look good, get decent gas mileage, etc.

but to my "needing guidance"

what sort of mechanical upkeep is there? i understand there is a special oil for bikes due to the engine and transmission sharing the same oil?

how is the gas mileage actually, say a CBRf4i?
local bike riding schools/classes?
best suggested equipment for when i do drop it? (i work in a warehouse most the time, so i can bare some heat to save my skin)
any suggested parts to help prevent damage? thought i recall someone mentioning pegs or rollers or something to save the ferrings?
should i have an issue, are the older bikes easier to work on, say pre 96?
insurance, what is with this, do i need it?
motorcycle liscenses?

like i said, total newbie, if i missed a post where this is all explained, please direct me toward it.
